Edinburgh EPLED Series

Picosecond pulsed UV & VIS LED's

Edinburgh Instruments

These picosecond pulsed LEDs are ideal excitation sources for a wide range of spectroscopy applications as well as being stand-alone modules.


  • Sub-nanosecond pulsed LED light source
  • Optimised for TCSPC
  • Pre-set Repetition Frequencies from 20 KHz to 20 MHz
  • External Trigger Facility
  • Optimised Collimated Beam
  • Spectrally Purified Output
  • Built-In Drive Electronics

Pulsed light emitting diodes of the EPLED series produce sub-nanosecond (typically <750ps) optical pulses at repetition rates up to 20MHz and are therefore ideally suited to Time-Correlated Single Photon Counting (TCSPC) measurements. In TCSPC , they bridge the gap between the nanosecond flashlamp and the expensive mode-locked titanium sapphire femtosecond lasers. EPLEDs are fitted with bandpass filters for spectral purity and are available with emission covering the UV-Visible spectrum, starting from 250nm.

Other picosecond pulsed light emitting diodes may also be used. Please enquire for integration options that are available.
